MCE IR blaster

[fuzzweed]

I've got some hauppauge ir blaster cables, and an MCE IR receiver unit. unfortunately the HP blasters have too small a plug on them to fit the MCE receiver. I'm guessing I can just snip the blasters off the HP plug and solder them onto a larger jack plug and it'll work in the MCE receiver, but what should the correct MCE blaster plug look like? It looks like a 3.5mm headphone type socket, but is it two or three connections (mono or stereo type headphone jack)???
